MNPDNashville/Twitter(NASHVILLE) -- A manhunt is underway to track down a fired gym employee who allegedly killed a co-worker with a hatchet, Metro Nashville Police Department officials said.

Authorities said that Domenic Micheli, 36, showed up at his former Balance Training gym workplace Monday morning with a hatchet and allegedly stabbed his former supervisor -- who has been identified by Nashville police officials as 46-year-old Joel Paavola.

Nashville police issued a tweet reporting that Paavola apparently fired Micheli in early 2017.

In a subsequent tweet that included a recent photo of Micheli with a full-grown beard, police said he is believed to be driving a gold-colored "older model Toyota Yaris."

"This picture more closely resembles what Domenic Micheli looks like now," police tweeted.
